The object -of my ',inventi-onis to provide a wheel rim thatLshall-becomposed -o'f .several parts ycapable of ready. manipulation A,and whichshall :adapt the to any yof several Patented Sept.;29, 1908.

\ D., 4openat one point D', as shown in 1. Be it known that' I.,- EnnsvBAKER., .a citiy vzen ofthe IUnitediStates, and ya resident of This-ringis provided with an annular 'bead lor tongue, D, which fits in thegroove, C

on the flange, the means which I prefer to employ for this purpose beingan endless ring Which takes one ofthe two forms, E and E', shown inFigs.' 2 land 3, such form depending upon the shape ofv the tire `onwhich lthe yrimis to be used. The essential point is thatlfat yleastyone flange of the rim is detachable. YIt is obvious that suchdetachable flanges may be used upon both sides oredges lof the rim. Thering, E in Fig. 3 serves to secure the 'detachable flange, D, on the riml.as expanded. It also serves another purpose, namely, to-Wit: it formsa curl over the edge of lthe clencher flange ringand protects the tire,A, therefrom., affording a Wide curved surface over which the tire maywork vWithout danger of being cut by the rim. The firing, E4" may 'be`either endless or `split as it lits Within the integral flange of therim.

With respect to the tire it serves the same purpose as the ring, E. Itwill be noted that the rim shown in Fig. 2 is a clencher rim, Whereasthe tire A mounted thereon is of the non-clencher type. To `adapt theclencher rim to receive such a tire I employ the fillers lor fillerrings, E, EX. The ring, E, `serves the double purpose yof a filler and alock for thedetachable flange, D. As explained it is preferably endless.Thefring, @Shaving no'locking function is purely a filler which occupiesthe clencher groove in the rim and provides a'substantially straightsurface or flange to receive the side of the itire A. yThering, EX, maybe endless oropen -as desired. The fillers preferably extend .above :orupon the clenching edges of thel rim fand protect the sides of the tiretherefrom in the same manner and to the same vend as explained' inconnection with Fig. 3. The

forms and sizes of the fillers are determined by the forms and sizes ofthe rims and tires to be used.

As various modifications of the invention `will readily suggestthemselves to one skilled in the art, I do not confine the invention to,the `specijic structures herein shown and described.

Having thus described my invention, I claim as neWand desire to secureby Letters Patent: p

1. A lc'l-encher rim having a removable l In( flange and a filler ringadapted to fill the s ace in one of said flanges and extending ove orbeyond the edge thereof to protect a .non-clenchertire from said edge,substantially as described.

2. A clencher. rim having a removable flange, in combination with a ringoccupying the groove in one of the flanges of the rim and extending overand around the edge of 10 the flange to form a curved seat for :L tire lwhen compressed or deflated, substantially es described.

In testimony whereof, l have hereunto set my hand, this 16th day ofJuly, 1906, in tho presence of two subscribing witnesses.
